I'm a little concerned about the solder joints on the two marked resistors (the 15K ones near the transformer). It does not look like the solder flowed through the board. I am also a little concerned about the solder joints on the back of the big capacitor.
I prefer to work with a really hot iron and move fast - as soon as the solder metls and flows, it's time to move on. Usually ~3 seconds or less per joint for the small stuff: resistors, capacitors, sockets, and such. If you have to keep the iron in place for more than 10 seconds for the solder to melt, it's either not hot enough, not stong enough (wattage), or you are working a heavy joint - like the spade lugs on the MR-16 or the fuse socket...
One other thought, if you have a multimeter, you may want to check the 3.3 and 5 volt regulators to make sure you didn't swap them. They look a lot alike and you really cannot tell once the heat sink is attached.
Good luck!!
